[TYPO3-mvc] creating nodes in FLUID - how to?

I think this is not really needed.

As I understand your problem, you can use the
"ViewHelperVariableContainer" to pass information between ViewHelpers -
example:

<f:a>
	<f:b></f:b>
</f:a>

If f:a needs some value which is set by b, B does the following inside
its render method:
$this->viewHelperVariableContainer->add('Tx_Fluid_ViewHelpers_BViewHelper',
'myidentifier', 'value');

A can access that value like so:
$this->renderChildren() // We need to render children first so that the
				// viewHelpervariablecontainer is filled
$valueOfMyIdentifier =
$this->viewHelperVariableContainer->get('Tx_Fluid_ViewHelpers_BViewHelper',
'myidentifier');

With this possibility, you can also pass arrays etc.

Greets,
Sebastian
